症候性総頚動脈閉塞症に対する大伏在静脈を用いたボンネットバイパス術の 1 例

Abstract

We herein show a case of symptomatic common carotid artery occlusion that underwent bonnet bypass (contralateral superficial temporal artery (STA) -saphenous vein (SV) -cortical segment (M4) of the middle cerebral artery (MCA) bypass) using an SV graft. STA-MCA bypass surgery has been established for the prevention of secondary cerebral infarction of symptomatic internal carotid artery occlusion. On the other hand, there has been no standard surgical treatment for symptomatic common carotid artery occlusion. It has been reported that bonnet bypass using donor grafts is effective for these pathological conditions. We herein performed bonnet bypass surgery using an SV graft as a donor graft. The vascular reserve was improved in quantitative single photon emission computed tomography, the bypass patency was also spared, and the postoperative course was uneventful.
